ABSTRACT:
In a fuel injection nozzle for an internal combustion engine, a valve needle and a valve needle spring are provided, in which the valve needle can be opened against the force of the valve needle spring (6). In the valve needle spring chamber (8) a displacer piston (7) is arranged so as to overlap the valve needle spring (6), which piston clears a displacing volume after a pre-injection so that the pre-injection is separated from the main injection.
